bios update and lockout

Hello Expert,

I recently update the BIOS of a workstation that is part of a network
After the update, the user of the workstation is  frequently lock out despite not exceeding his account’s logon attempts  threshold.
This threshold is set to three attempts.
I am confuse, I check all his account parameters and everything is okay.
Could updating the BIOS change a workstation SID or corrupt a user profile ?

Thank you

I have seen this happen b4. I had to unjoin the machine to the network and rejoin to resolve. I think it does soemthing with the computer account profile or maybe the sid.

Flash it back to the original version and see if it makes a difference.  You should avoid flashing a BIOS unless it is absolutely necessary, because it is not without risk, and may introduce new problems.

If SID is the issue, the user maybe not able to login at all.

As the issue seems with frequent user account lockups, try the user login into a different machine to see if it happens. As said by marine, unjoin and rejoing the machine to the domain controller.
